Do Juve buy the shirts from Adidas first and then resale for a profit from their stores ? if so what is the marginal profit per shirt?
Probably more than 40%. You can roughly calculate it from financial report:
Revenues from sales of products and licences - 16/17 19.2M 15/16 13.5
Purchases of products for sale - 16/17 8.3 15/16 4.3
in 16/17 we earned 19.2 paying 8.3 (43% of 19.2) to adidas for providing the products. Keep in mind that we are probably have other partners who might be included in this numbers.
Anyway it means we can get 57% of the final sale, but it doesnt include the other costs (personel etc.).
Anyway the 520k rumour was bullshit. It would have to be like 500k from our online store and the rest from local shops. I heard about interview with one Adidas shop owner in Italy and he called it bullshit since the shops usually dont have more than few hundreds of shirt on stock so it was impossible to sell so many of them in one day.
However its seems possible that we sold 300k so far from our channels.
